Walbro 255 + evo 510's or 550's + 14b@16-18psi, what am i missing?

[Race94]

Do i need an AFPR if i have the larger inyectors?
Do i need an S-AFC for 550's? 510cc?

I'm running a 14b @ 16psi-18psi with all bolt ons + a 255lph pump and stock everything else

Thanks

You need an AFPR for the larger pump and yes you need an S-AFC to control the larger injectors.

You will need an AFPR with the 255...also stick with 550cc's not 510's and then use an SAFC to tune from there

sounds like the first stage of my new project

94 w/jdm 6bolt, eprom studder stepped ECU, X-clutch, safc

having an Evo fmic piped in and installing the pump and injectors in the next week

510's are small enough that you can get away with out using an afc, at least on a 1g. I don't know if the 2g ecu would be any diffrent on controlling the injectors. being that your a 2g I would suggest a afpr when running a 255. 550's would be better but if you have no cash for an afc but have the 510's in hand, I would throw the 510's in for now.
